KTR-N 49011 EN Torque Measuring Shaft Sheet: 5 of 19 Operating/Assembly instructions Edition: 9 2 Advice 2.1 General advice Please read through these operating/assembly instructions carefully before you start up the measuring shaft. Please pay special attention to the safety instructions! The operating/assembly instructions are part of your product. Please store them carefully and close to the meas- uring shaft. The copyright for these operating/assembly instructions remains with KTR. 2.2 Safety and advice symbols This symbol indicates notes which may contribute to pre- Warning of potentially explosive venting bodily injuries or serious bodily injuries that may atmospheres result in death caused by explosion. This symbol indicates notes which may contribute to pre- STOP Warning of personal injury venting bodily injuries or serious bodily injuries that may result in death. This symbol indicates notes which may contribute to pre- ! Warning of product damages venting material or machine damage. This symbol indicates notes which may contribute to pre- General advice venting adverse results or conditions. 2.3 General hazard warnings With assembly, operation and maintenance of the measuring shaft it has to be made sure that the entire drive train is secured against accidental switch-on. You may be seriously hurt by rotating parts. Please make absolutely sure to read through and observe the following safety indications. All operations on and with the measuring shaft have to be performed taking into account "safety first". Please make sure to switch off the power pack before you perform your work on the measuring shaft. Secure the power pack against accidental switch-on, e. g. by providing warning signs at the place of switch-on or removing the fuse for current supply. Do not reach into the operation area of the measuring shaft as long as it is in operation. Secure the rotating components of the measuring shaft against accidental contact. Please provide for the ne- cessary protection devices and covers. 2.4 Intended use You may only assemble, operate and maintain the measuring shaft if you have carefully read through the operating/assembly instructions and understood them had technical training are authorized by your company The measuring shaft may only be used in accordance with the technical data (see table 1 to 3). Unauthorized modifications on the measuring shaft are not admissible. We will not assume liability for any damage that may arise. In the interest of further development we reserve the right for technical modifications. The DATAFLEX® torque measuring shaft described in here corresponds to the technical status at the time of printing of these operating/assembly instructions.

Both DATAFLEX® and RADEX®-NC can be stored at a dry and covered place for 6 - 9 months. Humid storage rooms are not suitable. Please make sure that condensation is not generated. The best relative air humidity is less than 65 %. 3.1 Storage The RADEX®-N couplings are supplied in preserved condition. Both DATAFLEX® and RADEX®-N can be stored at a dry and covered place for 6 - 9 months. Humid storage rooms are not suitable. Please make sure that condensation is not generated. The best relative air humidity is less than 65 %. 3.2 Transport and packaging In order to avoid any injuries and any kind of damage please always make use of proper transport and lifting equipment. ! The couplings are packed differently each depending on size, number and kind of transport. Unless otherwise contractually agreed, packaging will follow KTR's in-house packaging specifications. 4 Assembly The measuring shaft and the couplings are supplied as single pre-assembled component assemblies. Before assembly the measuring shaft along with coupling has to be inspected for completeness. The mounting position of DATAFLEX® is variable. The measurement system can be mounted both horizontally and vertically. 4.1 Components of DATAFLEX® torque measuring shaft ® Components of DATAFLEX torque measuring ® Components of RADEX -NC coupling shaft Com- Com- Quantity Component assembly Quantity Component assembly ponent ponent ® DATAFLEX torque measu- ® 1 1 2 2 RADEX -NC type EK ring shaft Illustration 3: DATAFLEX® 22 torque measuring shaft with RADEX®-NC Please observe protection Drawn: 2017-01-02 Shg/Koe Replacing: KTR-N dated 2013-09-03 note ISO 16016.

If these figures are disregarded, the coupling may tear. Ro- tating particles may cause danger to life. Clamping hub bores machined by the customer have to observe concentricity or axial runout, respectively (see il- lustration 4). Please make absolutely sure to observe the figures for Ø d1max and Ø d2max. Carefully align the clamping hubs when the finish bores are drilled.
